Struts 2 simple success page doesn't direct on class SampleAction

Question

I have followed a tutorial in youtube by about struts I completely followed every step but I have a problem my program doesn't direct me to the class. I know that it doesn't direct because it does not show the message System.out.println("from execute");

Here is my code:

struts.xml:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE struts PUBLIC
    "-//Apache Software Foundation//DTD Struts Configuration 2.3//EN"
    "http://struts.apache.org/dtds/struts-2.3.dtd">

<struts>
    <package name="default" extends="struts-default">
        <action name="sample" class="com.struts.sample.action.SampleAction">
            <result name="success">/success.jsp</result>
            <result name="error">/error.jsp</result>
        </action>
    </package>    
</struts>

web.xml:

<?xml version="1.0" encoding="UTF-8"?>
<web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" id="WebApp_ID" version="3.0">

        <filter-name>struts2</filter-name>
        <filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
    </filter>

        <filter-name>struts2</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>  
</web-app>

SampleAction.java:

package com.struts.sample.action;

public class SampleAction {

    public String execute(){

        System.out.println("from execute");
        return "success";
    }

}

success.jsp:

<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
    pageEncoding="ISO-8859-1"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
success
</body>
</html>

I'm getting this output:

HTTP Status 404 - There is no Action mapped for namespace [/] and action name [getTutorial] associated with context path [/Struts2Example].

Type Status report:

message There is no Action mapped for namespace [/] and action name [getTutorial] associated with context path [/Struts2Example].

description The requested resource is not available.

This is my console:

There should be something like "from execute" in the console because of this System.out.println("from execute"); but it does not go in the class I don't know how to debug it anymore. enter image description here

Was it helpful?

Solution 2

what i did was to delete the saved jar in WEB-INF/lib i think my problems was because i had double jar one from the tutorial way and the other was because i had paste the same jar in the said folder.jar redundant my have cause my problem so if you have done the same delete the saved jar and rerun the program it will work for sure

OTHER TIPS

You have WEB-INF/class should be renamed to WEB-INF/classes. In the the package explorer right click on the folder name and choose rename or refactor/rename. If this doesn't work open a resource perspective and rename the folder name. After that clean and rebuild and redeploy the project.
